I personally do not think "full spectrum" lights will have any noticeable growth benefit. There is a well established science behind using red lights to grow plants/algae more efficiently, but more efficiently does not mean faster. It just means it uses less power. I think the use of multi-color LEDs serves more to improve appearance of corals.

Totally agree with you, I have 2 sols on my 90g and they work great for me so far. I have had no issues with original controller.
